摘要:
An IR supercontinuum source for generating supercontinuum in the MIR or possibly LWIR spectral bands comprises a supercontinuum fiber formed from a heavy metal oxide host glass having low optical loss and high non-linearity over the spectral band that is stable, strong and chemically durable. The supercontinuum fiber is suitably a depressed inner clad fiber configured to support only single transverse spatial mode propagation of the pump signal and supercontinuum. The source suitably includes a tapered depressed inner clad fiber to couple the pump signal into the supercontinuum fiber. The source may be configured as an “all-fiber” source.
摘要:
A tellurium oxide glass that is stable, strong and chemically durable exhibits low optical loss from the UV band well into the MIR band. Unwanted absorption mechanisms in the MIR band are removed or reduced so that the glass formulation exhibits optical performance as close as possible to the theoretical limit of a tellurium oxide glass. The glass formulation only includes glass constituents that provide the intermediate, modifiers and any halides (for OH— reduction) whose inherent absorption wavelength is longer than that of Tellurium (IV) oxide. The glass formulation is substantially free of Sodium Oxide and any other passive glass constituent including hydroxyl whose inherent absorption wavelength is shorter than that of Tellurium (IV) oxide. The glass formulation preferably includes only a small residual amount of halide.

摘要:
Ceramic fibers comprising glass, and composites comprising such fibers. The glass comprises at least 35 percent by weight Al2O3, based on the total metal oxide content of the glass, a first metal oxide other than Al2O3, and a second, different metal oxide other than Al2O3. The glass contains not more than 10 percent by weight collectively As2O3, B2O3, GeO2, P2O5, SiO2, TeO2, and V2O5, based on the total weight of the glass. The first and the second metal oxides are each selected from the group consisting of Y2O3, REO, MgO, TiO2, Cr2O3, CuO, NiO, Fe2O3, ZrO2, HfO2 and complex metal oxides thereof. At least a portion of the glass may be converted to crystals.

摘要:
An optical fiber, which has a zero-material dispersion wavelength equal to or greater than 2 μm, and a high nonlinear susceptibility χ3 equal to or greater than 1×10−12 esu, and uses tellurite glass having sufficient thermal stability for processing into a low loss fiber, employs a PCF structure or HF structure having strong confinement into a core region. This enables light to propagate at a low loss. The size and geometry of air holes formed in the core region, and the spacing between adjacent air holes make it possible to control the zero dispersion wavelength within an optical telecommunication window (1.2-1.7 μm), and to achieve large nonlinearity with a nonlinear coefficient γ equal to or greater than 500 W−1 km−1.
摘要:
Disclosed is a method of doping an oxide. The example method includes forming at least one of an AlGaAs oxide or an InAlP oxide on a GaAs substrate, and incorporating Erbium into the at least one AlGaAs oxide or InAlP oxide via ion implantation to form an Erbium-doped oxide layer. The example method also includes annealing the substrate and the at least one AlGaAs oxide or InAlP oxide.

摘要:
A heavy metal oxide glass selected from germanate, tellurite and bismuth oxide glasses provides a host for highly efficient Thulium doped 2 μm oxide glass and fiber lasers. The concentration of Thulium ions is high enough that energy transferred by the phenomenon of cross-relaxation will enhance laser emission at 2 μm and suppress emission at 1.5 μm so that 2 μm emission is dominant.
